--4 Claims. (Cl. 24-134) .This invention relates to a grip for a cableor the like, the general object of the invention being 'to provideadevice which can be easily and quickly attached to and detached from acable or the like and which canbe used for, a great number of: differentpurposes, and the greater the pull exerted upon the'device, the firmer,the. jaws of the device will grip the cable ,or other member.

This invention also consists in certain other featuresof constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustratedin the accompanying drawings andspecifically pointed out in: the appended claims. I I

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts, throughout the several views, and in which:-

Figure 1 is an elevation of the device.

Figure 2 is an edge view thereof.

Figure 3 is a section on line 3-3 of Figure 2.

Figure 4 is a section on line 4-4 of Figure 1.

Figure 5 is a section on line 5-5 of Figure 3.

Figure 6 is a fragmentary view showing modified forms of jaws.

In these drawings, the numeral 1 indicates the body of the device whichis reinforced by ribs 1', and said body is formed with a chamber 2 forthe jaws and their operating means and with a slot 3 for the entrance ofthe member to be gripped, this slot passing through the front face ofthe body. A pair of studs 4 passes through the body from rear to front,through the chamber and forms bearings for the eccentrics 5, each ofwhich is encircled by an eccentric strap 6 having a projection 7 thereonto which a jaw 8 is pivoted, as shown at 9. An arm 10 is connected toeach eccentric, said arms extending through openings in the sides of thebody and have holes 11 at their outer ends for receiving the ends of thechains 12, the other ends of the chains being connected to a ring 13 anda cable or pulling member 14 has one end connected to the ring. Insteadof using the chains 12, links may be used.

Thus it will be seen that by passing a cable or other member through theslot 3, with a portion of the member passingbetween the jaws,

.and then exerting a pull upon the member 14, the chains 12 will swingthe arms 10 upwardly so that the jaws will move toward each other andthus the jaws will grip the cable or other member so that the saidmember is connected to the body. Then a further pull on the member 14will exert a pull upon the cable or member gripped by the jaws 8.

A member 15 is connected to a triangular member 16 which in turnisconnected to the body 1 by the clevises 1'1 and byslackening themember 14 and exertinga pull upon the member, 15, saidbody 1 willbemoved while the member grippedby the jaws8 is held stationary and thusthe arms 10 will-.move the jaws to releasing position. I

Projections 18 are are engaged by pins 19 on the arms 10 forlimiting-opening movement of the arms. When the device is used for heavywork, a strain link or 4 and held thereon by the cotter pins 21 passingthrough the front ends of the studs, this plate or link strengtheningthe parts. When it is not desired to use this link, it can be removedand I the cotter pins placed in the holes 22 formed in the front ends ofthe studs, as shown in Figure 5,

to hold the studs in place.

In order to prevent the cable or member to be gripped from moving out ofthe slot 3 before the jaws are moved to clamping position, I provide asubstantially U-shaped bar or safety link 24 which has its ends fittingbetween the projections 23 formed on the front face of the body and thislink or bar is held in place by the pins 25, which in turn are held inposition by the cotter pins 26.

When desired, this safety link 24 can be removed and only the pins 25used to hold the cable in position.

The gripping edges of the jaws 8 may be-formed to suit the work to bedone by the device. For W instance, Figure 3 shows the jaws providedwith grooved gripping edges, as at 8, while Figure 6 shows the jawsprovided with projections 8" for gripping a link of a chain, forinstance.

As before stated, this device can be used in various situations and indifferent ways according to the wishes of the user, and as will be seen,the greater the pull upon the device, the firmer the jaws will grip thecable or other member.

The front wall of the chamber 2 is formed with '0 the pairs of inwardlyconverging shoulders 27 which form guides for the portions 7 so that thegripping jaws are moved in a straight line, with their gripping edgesremaining parallel during their opening and closing movements and, asshown in the drawings, the pivots 9 are formed with the jaws. It will beseen that the link or plate 20 acts to hold the cable in position whilethe member 24 is being put in place.

The extended upper and lower ends 28 of the formed on the body land Iplate 20 is placed over the front ends of the studs lower member of thebody can be used as anvils for making repairs and the like and theseparts are provided with the holes 29 which may be used for differentpurposes and also used for attaching the body to a supporting memberwhen it is desired to hold the body stationary.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

What is claimed is:

1. A device of the class described comprising a body having a chambertherein and a longitudinally extending slot passing through the frontface of the body, a pair of jaws in the chamber for gripping a memberpassed through the slot, eccentrics pivotally arranged in the chamber,straps for engaging the eccentrics and having projections to which thejaws are pivoted, outwardly extending arms connected to the eccentrics,a pull member, means for connecting the arms to the pull member, asecond pull member, means for connecting the same to the body.

2. A device of the class described comprising a body having a chambertherein and a longitudinally extending slot passing through the frontface of the body, a pair of jaws in the chamber for gripping a memberpassed through the slot, ec-

centrics pivotally arranged in the chamber, straps for engaging theeccentrics and having projections to which the jaws are pivoted,outwardly extending arms connected to the eccentrics, a pull member,means for connecting the arms to the pull member, a second pull member,means for connecting the same to the body, a safety link detachablyconnected to the front of the body for holding the member to be grippedby the jaws therein, and a strain link detachably connected to theeccentric pivots.

3. A device of the class described comprising a body having a chambertherein and a longitudinally extending slot passing through the frontface of the body, a pair of elongated jaws in the chamber for gripping amember passed through the slot, eccentrics pivotally arranged in thechamber, straps for engaging the eccentrics and having projections towhich the jaws are pivoted, guiding means for causing the jaws to remainparallel during their movements, outwardly extending arms connected tothe eccentrics, a pull member, means for connecting the arms to the pullmember, a second pull member, and means for connecting the same to thebody.

4. A device of the class described comprising a body having a chambertherein and a longitudinally extending slot passing through the frontface of the body, a pair of elongated jaws in the chamber for gripping amember passed through the slot, eccentrics pivotally arranged in thechamber, straps for engaging the eccentrics and having projections towhich the jaws are pivoted, guiding means for causing the jaws to remainparallel during their movements, outwardly extending arms connected tothe eccentrics, a pull member, means for connecting the arms to the pullmember, a second pull member, means for connecting the same to the body,and upper and lower extensions formed on the body forming anvils andhaving holes therein.
